Seachem Laboratories Reef Kalkwasser
Information

Seachem Reef Kalkwasser is a pure calcium hydroxide with unsurpassed purity and solubility characteristics. This calcium hydroxide meets or exceeds the purity of competing brands designated for reef use. Calcium hydroxide is used to prepare limewater (kalkwasser) solutions that are used in an automated dosing system that replaces evaporated water. Kalkwasser solutions maintain calcium directly and carbonate alkalinity indirectly. However, its capacity to perform these functions is dependent on evaporation rate and CO2 concentration. If these two factors are insufficient you can provide additional calcium with Reef Advantage Calcium, Reef Complete, or Reef Calcium, and carbonate alkalinity with Reef Builder or Reef Carbonate (do not mix these directly with a kalkwasser solution). Reef Kalkwasser can also precipitate phosphates and impurities from the makeup water while maintaining a high pH which is important for proper calcification rates and for oxidizing various organics in reef aquaria. 500 g makes 650 L (166 gallons) of kalkwasser solution.

SeachemSeachem Laboratories, Inc. was established in 1980 by Dr. Leo G. Morin. Seachem moved into a state of the art 110,000 square foot facility in Madison, Georgia marking their 25th anniversary in the industry in 2005. This facility includes production and research laboratories, manufacturing, inventory, shipping, and office space.

Comments:I use 1/2cup of this product a week in my kalkwasser reactor (a must if you're serious about the health of a reef tank) and my pH & calcium levels are as steady as one could hope for. This is very simple to use if you have a kalkwasser reactor, but I wouldn't suggest this product to a beginner as overdosing could harm the health of one's system. I am giving it 4 stars because I haven't used the whole bottle yet, and am waiting for completion of product before I praise it further.

Comments:I use 2kg of this a year and it is great. The price is right. It does not clump up in my kalkstirrer, other brands with Mg did. I refill the stirer monthly, dose with a litermeter III and by it alone keeps Ca=400, Ph 8.4 in a 180g SPS + clam reef.

Comments:I am using this product to maintain Ph on a 125 mixed reef...It is super loaded and has a tendency to drop in Ph....This product mixes well and settles fast. I am using it in a 2.5 gal aquadoser. I just set it on the top of the hood to my tank and drip away....Corals are more colorful and "hairy" (SPS) and polyps are more extended...(LPS). Inexpensive, great product...the bigger 4 L has a lid that is a bugger to open, but that is overcome with continued use....
